This study was aimed at determining the cephalic length, cephalic breadth and cephalic index of the
Ibibios of Nigeria, which would be useful in clinical practice, forensic medicine, anthropology and genetic
study. The study was carried out using 800 subjects of Ibibios who were between the ages of 18 – 80years,
comprising of 400(four hundred) males and 400(four hundred) females. The subjects which were Ibibios by
both parents and grandparent were randomly selected. The cephalic length (CL), cephalic breadth (CB) and
cephalic index (CI) were determ ined using standard methods. The data obtained showed that the mean values
of the CL, CB and CI were 19.06±0.77cm, 15.20±0.71cm and 79.85±4.05 respectively for males and
18.80±0.77cm, 14.70±0.67cm and 78.36±6.12 respectively for the females. The CI shows that Ibibio males and
females belong to the mesocephalic group. The mean value of CL, CB, and CI for Ibibios (male and female)
were 18.93±0.79cm, 14.95±0.73cm and 79.11±5.24 respectively. Statistical analysis using z-test indicated that
significant difference exists between the males and the females with males showing higher values in all the
parameters (p<0.05). This data is expected to be of clinical, forensic, anthropological and genetic importance
importance.
